Electronic Data Interchange (EDI)

Simplifying electronic claims submission

What is EDI?

Electronic data interchange (EDI) is a powerful tool for increasing office productivity and improving cash flow. The benefits of the EDI services offered by AmeriHealth include:

  • Faster processing and timely error reporting for claims
  • Automated posting of claim payments
  • Real-time verification of a patient’s coverage and cost-sharing responsibility

Getting started with EDI

Highmark, Inc. (Highmark) provides the Highmark Gateway to handle EDI transactions on behalf of AmeriHealth. You may conduct EDI transactions directly with the Highmark Gateway by registering as a new trading partner. Alternatively, you may contract with a third party that has an existing trading partner relationship with Highmark, such as a billing service or clearinghouse.

To start conducting EDI business with AmeriHealth, please take the following steps:

  • Get your NPI and register it with AmeriHealth.
  • Select a trading partner or sign up as your own trading partner.
  • Affiliate your NPI with your trading partner to enable electronic transactions.

Upcoming EDI Gateway transition

Over the next year, AmeriHealth HMO, Inc. and AmeriHealth Insurance Company of New Jersey will transition Electronic Data Interchange (EDI) transactions from the Highmark EDI Gateway to Smart Data Solutions (SDS) Stream Clearinghouse.

This is an initial step of our transition to a next generation platform that will help us operate more efficiently and deliver new and innovative products and services. Learn more.
